[0004] The above solution requires users to manually switch the heating mode, which is not smart enough and will result in a poor user experience. Moreover, users manually switch the heating mode according to their own feelings of hot and cold, which cannot maximize energy utilization and easily causes energy waste, resulting in high energy consumption and uncontrollable heat source costs. In addition, if furnaces are used extensively for heating, it may lead to excessive greenhouse gas emissions produced by the combustion of natural gas.

[0050] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0051] Example 1

[0052] The dual heat source device involved in this embodiment integrates an air source heat pump and a natural gas furnace, and can be heated by an air source heat pump or a natural gas furnace, that is, the heating mode of the dual heat source device includes heat pump heating and furnace heating. In actual use, the user can choose to manually switch the heating mode, or enable the automatic heat source switching function, and automatically switch the heating mode through the heating control method of this embodiment.

[0053] This embodiment provides a heating control method for a dual heat source device. Figure 1 is a flow chart of a heating control method for a dual heat source device provided by an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0054] S101, determining whether the current outdoor temperature is less than or equal to a preset temperature.

[0055] S102: If the current outdoor temperature is less than or equal to the preset temperature, use the furnace for heating.

[0056] S103: If the current outdoor temperature is greater than the preset temperature, the heating method to be used is determined according to the current gas cost and electricity cost.

[0057] S104, during the heat pump heating period, controlling the switching of the heating mode according to the heat pump operation status.

[0058] S105, during the furnace heating period, controlling the switching of the heating mode according to the furnace operation time and the outdoor temperature.

[0059] Among them, the preset temperature can be set according to the climate conditions of the location of the dual heat source equipment or the actual needs of the user. For example, the staff sets it when installing the dual heat source equipment, and / or the user sets it by himself when using the dual heat source equipment.

[0060] Furnace heating heats the room by burning natural gas, while heat pump heating heats the room by using the heat generated by the operation of the compressor. In the same amount of time, furnace heating will raise the indoor temperature faster than heat pump heating.

[0061] If the current outdoor temperature is less than or equal to the preset temperature, it means that the current outdoor temperature is low. At this time, the furnace is used for heating first to ensure that the indoor temperature quickly reaches the target temperature set by the user, so that the user can quickly feel the temperature is comfortable.

[0062] If the current outdoor temperature is greater than the preset temperature, a more cost-effective heating method is determined based on the current gas cost and electricity cost as the current heating method to be used, so as to reduce heating costs and energy consumption.

[0063] During heat pump heating, the switching of heating modes is controlled according to the operation status of the heat pump. During furnace heating, the switching of heating modes is controlled according to the furnace operation time and the outdoor temperature. This enables the timing of switching heating modes to be more accurately grasped according to the actual operation status of the equipment, thereby maximizing energy utilization while meeting the heating needs of users.

[0064] This embodiment is aimed at dual heat source equipment, and controls and switches the heating mode according to the outdoor temperature, gas cost, electricity cost and actual operation of the equipment. When the current outdoor temperature is less than or equal to the preset temperature, furnace heating is given priority to ensure that the user's heating needs are quickly met; when the current outdoor temperature is greater than the preset temperature, a more cost-effective heating mode is determined according to the current gas cost and electricity cost as the heating mode currently required to be used, so as to reduce heating costs and energy consumption; and the switching of the heating mode is controlled according to the actual operation of the equipment during heat pump heating and furnace heating, so that the switching timing of the heating mode can be grasped more accurately, and the energy utilization rate can be maximized while meeting the user's heating needs; there is no need for the user to manually switch the heating mode, and the heating mode is automatically and intelligently switched to the heating mode with the best cost and heating efficiency, thereby reducing energy loss, avoiding excessive greenhouse gas emissions due to excessive use of furnace heating, improving user experience, and solving the problem in the prior art that the dual heat source equipment requires the user to manually switch the heating mode, resulting in high energy consumption and poor user experience.

[0065] In one embodiment, the heating method currently required to be used is determined based on the current gas cost and electricity cost, including: calculating the current gas cost and electricity cost; if the current gas cost is greater than or equal to the current electricity cost, using a heat pump for heating; if the current gas cost is less than the current electricity cost, using a furnace for heating.

[0066] This embodiment automatically selects a lower-cost heating method when the current outdoor temperature is greater than a preset temperature, which can reduce heating costs and energy losses.

[0067] Specifically, the current gas cost can be obtained by calculating the ratio of the current gas unit price to the furnace efficiency. The gas cost represents the efficiency of natural gas furnace per cubic meter (m 3 ) The actual gas cost required. Specifically, the current electricity cost can be obtained by calculating the ratio of the current electricity price to the heat pump heating efficiency, which represents the actual electricity cost required per kilowatt-hour (kWh) of the air source heat pump. Considering the efficiency of the furnace to calculate the actual gas cost and the energy efficiency of the heat pump to calculate the actual electricity cost can ensure that the comparison results of the gas cost and the electricity cost are more referenceable, which is conducive to the energy-saving control of dual heat source equipment.

[0068] Taking into account that the units of gas price and electricity price may be different, unit conversion is required. When the units of gas cost and electricity cost are consistent, the two can be compared to ensure comparability.

[0069] The user can input the gas unit price and electricity unit price through the thermostat. Specifically, the user can input the electricity price for different time periods on weekdays and holidays in different seasons, for example, the electricity price for different time periods on weekdays in summer or winter, and the electricity price for different time periods on weekends and holidays in summer or winter.

[0070] The furnace efficiency is the energy conversion efficiency of the natural gas furnace itself. Users can obtain it from the equipment nameplate or manual and enter it through the thermostat. The furnace efficiency can also be saved in the thermostat when the equipment leaves the factory. When the gas cost needs to be calculated, the stored furnace efficiency will be automatically read.

[0071] The heat pump heating efficiency is the ratio of the heat generated by the air source heat pump during the heating process to the electrical energy consumed. The heat pump heating efficiency COP corresponding to different outdoor temperatures and different power input powers can be pre-stored, and the COP corresponding to the current outdoor temperature can be automatically read when the electricity cost needs to be calculated.

[0072] During heat pump heating, the switching of heating modes is controlled according to the operation of the heat pump, including: determining whether a temperature point shutdown occurs within a preset time after entering the heat pump heating; if so, continuing to use the heat pump heating; if not, switching to furnace heating.

[0073] The preset time may be a factory default value or may be set by the user. Temperature point shutdown means that the heat pump stops running when the indoor temperature reaches a temperature point, which may be greater than or equal to the target temperature set by the user.

[0074] If the temperature point shutdown occurs within the preset time after entering the heat pump heating, it means that the heat pump is sufficient to meet the user's heating needs, and the heat pump heating can continue to be used; if the temperature point shutdown does not occur within the preset time after entering the heat pump heating, it means that the heat pump is insufficient and the current indoor temperature is still low. At this time, you can switch to furnace heating to increase the indoor heating rate.

[0075] In this embodiment, when heat pump heating is used based on cost considerations, the heating mode is switched within a preset time after the heat pump heating is started according to whether a temperature point shutdown occurs. This can ensure that the indoor temperature quickly reaches the target temperature set by the user, thereby quickly meeting the user's heating needs while also taking energy saving into account.

[0076] Furthermore, after continuing to use the heat pump for heating, the method further includes: when detecting that the outdoor temperature has changed, returning to the step of executing S101 to determine whether the current outdoor temperature is less than or equal to the preset temperature. In this embodiment, during the heat pump heating period, if the outdoor temperature changes, the judgment and switching can be re-performed in time, so as to switch to the best heating mode in time.

[0077] During furnace heating, the heating mode is switched according to the furnace running time and the outdoor temperature control, including: during furnace heating, recording the actual running time of the furnace heating; when the actual running time of the furnace heating reaches the shortest furnace running time, judging whether the current outdoor temperature is greater than or equal to the preset temperature + N; if the current outdoor temperature is greater than or equal to the preset temperature + N, switching to heat pump heating; if the current outdoor temperature is less than the preset temperature + N, returning to execute S101 to judge whether the current outdoor temperature is less than or equal to the preset temperature.

[0078] The minimum furnace operation time may be a factory default value or may be set by the user. N>0, preferably N=2, and the user may adjust the N value according to the heating comfort to obtain the best furnace heating experience.

[0079] In this embodiment, when the furnace is automatically selected for heating based on the heating speed or cost, the furnace heating is ensured to run continuously for a certain period of time during the furnace heating period to avoid frequent switching of heating modes and affecting the user experience. After the furnace heating has been running continuously for a certain period of time, the indoor temperature has been raised to a certain extent. If the outdoor temperature is greater than or equal to the preset temperature + N, it means that the outdoor temperature is not very low. In this case, it can be switched to heat pump heating to slowly increase the indoor temperature, thereby achieving both energy saving and user comfort experience.

[0080] Considering that the simultaneous operation of two heat sources results in higher energy consumption, only one heat source is used for heating at a time in the embodiment of the present invention.

[0081] Example 2

[0082] This embodiment uses a specific example to illustrate the heating control method of the dual heat source device. However, it is worth noting that this specific example is only for better illustrating the present application and does not constitute an improper limitation on the present application. The explanation of terms that are the same or corresponding to the above embodiment will not be repeated in this embodiment.

[0083] The dual heat source equipment includes a thermostat, which can display the operation of the heat pump and the furnace, and also allows the user to input and set the required parameters, such as the target heating temperature, etc. The thermostat uses the heat pump for heating by default.

[0084] like Figure 2 As shown, it is a schematic diagram of the heating control process, which includes the following steps:

[0085] S201, the user inputs the electricity price CER ($ / kWh) for each time period in summer and winter through the thermostat, for example, the peak and non-peak electricity price for each time period on weekdays and weekends in summer and winter. The user inputs the gas price UEGR ($ / m 3) and furnace efficiency GFE (%). The user sets the preset temperature T0, preset time t0 and the minimum furnace operation time t1 through the thermostat.

[0086] S202, detecting the current outdoor temperature T 外 , and determine whether T is satisfied 外 ≤T0, if yes, go to S206, if not, go to S203.

[0087] S203, the thermostat obtains the current electricity price CER and COP, and calculates the current electricity cost S1 = CER / COP. The thermostat calculates the current gas cost S2 = UEGR / (GFE / 100) / LNG, where LNG (kWh / m 3 ) represents the local conversion rule of natural gas kilowatt-hours and cubic meters, which links natural gas kilowatt-hours and cubic meters to facilitate the calculation of gas cost S2, making the units of gas cost and electricity cost consistent for easy comparison.

[0088] Determine whether S2≥S1 is satisfied. If so, proceed to S204; if not, proceed to S206.

[0089] S204, performing heat pump heating.

[0090] S205, judging whether a temperature point shutdown occurs within the time t0 of entering the heat pump heating, if so, entering S204 to continue the heat pump heating, if not, entering S206 to switch to furnace heating.

[0091] S206, heating by burning furnace.

[0092] S207, during the furnace heating period, after the actual operation time of the furnace heating reaches t1, determine whether T 外 ≥T0+N, if yes, go to S204 to switch to heat pump heating, if not, return to S202 to re-judge.

[0093] This embodiment is aimed at dual-heat source equipment, and can realize automatic intelligent switching between heat pump heating and furnace heating without manual switching by users, thereby improving user experience; the heating mode is controlled and switched based on outdoor temperature, gas cost, electricity cost and actual operation of the equipment, and furnace heating is given priority when the current outdoor temperature is less than or equal to the preset temperature, ensuring that the user's heating needs are quickly met; when the current outdoor temperature is greater than the preset temperature, a more cost-effective heating mode is determined based on the current gas cost and electricity cost as the heating mode currently required to be used, so as to reduce heating costs and energy consumption; and the switching of heating modes is controlled according to the actual operation of the equipment during heat pump heating and furnace heating, so that the timing of switching heating modes can be grasped more accurately, and energy utilization can be maximized while meeting the user's heating needs. This embodiment automatically and intelligently switches to the heating mode with the best cost and efficiency, reduces energy loss, avoids excessive greenhouse gas emissions due to excessive use of furnaces for heating, improves user experience, and solves the problem in the prior art that dual heat source equipment requires users to manually switch heating modes, resulting in high energy consumption and poor user experience, and effectively provides the best heating method to meet growing demand.
